A Fresh Look at the Wind-Moment Method

The wind-moment method (which has a long history of use) is explained as a branch of semi-continuous plastic design. By avoiding elaborate rigid connections, the method makes a substantial contribution to reducing the cost of unbraced frames. This is despite the relative flexibility of the joints, which influences lateral deflection and frame stability. Ways to account for this are suggested. The joints must, above all, be ductile, and the role of stundardised connections in meeting this requirement, and others, is described. It is concluded that the method, now more than ever, is appropriate for design of unbraced frames. A.F. Hughes, N.D. Brown and Professor D. Anderson
